How do I deal with an accumulation of Flurries?

Question

I have an iPhone app that has a relatively simple Flurry configuration installed. I notice that the Flurry files ("flurryResponseNNNNN...") seem to build up and are never deleted (at least not going back over 3 weeks).

Now, it is getting to be late enough in the year where we begin expect some accumulation here in Minnesota, but I'm not anxious for this much this early.

Is there some Flurry setting that controls the number of files (or total size or whatever) that Flurry retains, or do I need to manage this directly in my app?

Added:

The files are in the Documents directory. They contain XML similar to:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Answer 1

I should say that I discovered that these files are diagnostic logs, turned on by a setting when starting up Flurry. (I forget the specific setting and don't have the code at hand here, but it's fairly obvious when you go looking for it.) Turn off that setting and they go away (or at least no more are generated).
